The Question:

The Answer:

Actually, in classical Hebrew a "menorah" refers to a candelabrum of any
sort, not just the 7-branched one used in the Temple. A "hannukiah" or
"chanukiah" is a Modern Hebrew term for a menorah with nine branches.
It is a neologism; the
term did not exist until Ben-Yehuda came along in
the late 19th Century.

In the United States (where our site is based), the Chanukah candelabrum is almost
universally referred to among observant Jews as a menorah, not a
chanukiah, following the traditional usage.

Finally, every major English dictionary we've consulted includes
among the definitions of "menorah" both the nine-branched candelabrum
used on Chanukah and the seven-branched one used in the Temple.
